The limiting shaft 314 is fixedly connected with a pull rope 21, and one end of the pull rope 21 is fixedly connected to the auxiliary shaft 27.

The specific implementation process is as follows:

initially, the auxiliary shaft 27 is inserted into the main shaft 25 and compresses the first spring 26, and is attracted to the main shaft 25 by the first permanent magnet 28, so that the main shaft 25 and the auxiliary shaft 27 drive the support ring 12 to retract toward the longitudinal shaft 22, and the upper opening of the fishing net 11 is closed as much as possible.

After finishing the harvest of the fishing net part 11, the fishing net part 11 and the supporting ring 12 are thrown into the water, and at this time, the aquatic products (such as fish) do not enter the fishing net part 11 through the supporting ring 12. When reaching the designated position (such as water depth or water depth of a certain fish life), a certain amount of air is fed into the main shaft 25 through the air pump and the air pipe, the air enters the main shaft 25, the air pressure is matched with the elastic force of the first spring 26 to overcome the adsorption force of the first permanent magnet 28, and the first spring 26 pushes the main shaft 25 and the auxiliary shaft 27 to be separated, so that the support ring 12 is opened.

In the process, the fishing net part 11 and the supporting ring 12 are gradually moved upwards, and the supporting ring 12 and the fishing net part 11 are pulled to move upwards through the air pipe, the pulling ring 24 and the pulling part 23, so that fishes can enter the fishing net part 11 to achieve the purpose of fishing.

Of course, in this process, the auxiliary shaft 27 will drive the pull rope 21, the pull rope 21 pulls the limiting shaft 314, the second permanent magnet of the limiting shaft 314 is separated from the telescopic shaft 311 (the elastic layer will deform to reduce the obstruction of the conical groove) until the limiting shaft 314 abuts against the limiting block 315, under the action of the second spring 312, the telescopic shaft 311 will push the pulling piece 32 (overcome the resistance of the pulling piece 32 and the containing portion), the pulling piece 32 will drive the screen to gradually cover the supporting ring 12 (fan-shaped cover in the supporting ring 12) until the pulling piece 32 is adsorbed by the first permanent magnet 28, so that the supporting ring 12 is basically closed by the screen, the fish with larger body size can be reduced (to improve the catching efficiency), and the fish with smaller body size can be pulled out. Compared with the existing direct harvest of the fishing net, the method can reduce the probability of larger fish in the harvest process of the fishing net, and can not relate most of the seedlings to the fishing net.

In this embodiment, the screen mesh is temporarily applied to the fishing of the aquatic products having a small size or a small number, and the screen mesh is easily separated from the support ring 12 due to the limited resistance of the first permanent magnet 28, or the screen mesh is applied to the fish tank.
